Trifolium also called red clover is a plant. The flower tops are used to make medicine.It is used for many conditions, but so far, there isn't enough scientific evidence to determine whether it is effective for any of them. It doesn't seem to work, though, for lowering cholesterol or controlling hot flashes in women.It is also used for cancer prevention, indigestion, high cholesterol, whooping cough, cough, asthma, bronchitis, and sexually transmitted diseases (STDs).Some women use red clover for symptoms of menopause such as hot flashes; for breast pain or tenderness (mastalgia); and for premenstrual syndrome (PMS).Red clover is applied to the skin for skin cancer, skin sores, burns, and chronic skin diseases including eczema and psoriasis.
